MOTION-PICTURE APPARATUS.

Specification f Letters Patent.

Patented Sept. 10, 1907.

Application filed October 22,1906. Serial in. 339,988.

To all whom it may concern:

Be it known that I, CHARLES, FRANCIS JENKINS, a citizen of the UnitedStates, residing at' Washington, in the District of Columbia, haveinvented certain new and useful Improvements in lilotlon-PictureApparatus, of which the following is a specification.

This invention relates to that class of motion picture apparatus inwhich the pictures are on separate leaves bound in book form, andcommonly known as thumb books. It has been found impossible, inexhibiting these books manually, to let the leaves slip from under thethumb so smoothly and evenly-timed as to produce an entirelysatisfactory picture.

The object of this invention is to provide apparatus lor exhibiting thepictures of these thumb books with such precision and uniformity as toproduce gratifying results.

A further object of the invention .is to provide means whereby anynumber of these books can be'exliibited automatically, a number limitedonly by the convenicni'. size of the apparatus.

The means employed to this end are described in these specifications,and illustrated in the accompanying drawings, in which Figure 1 shows,in perspective, the general form of these thumb books i. 0., a number ofleaves bound togetlicr at one end by cloth, or the like, and stitchedthrough with wire, the leaves bearing a series of related pictures; Fig.2 a bent elevation of. the upper part of the apparatus; and Fig. 3 aside elevation.

In the drawings, A is a standard having a grooved I drum B rotatablymounted near the top thereof, the

drum having the gear C rigidly attached thereto, said I gear being inturn driven by the pinion D, rotated by any suitable means, as, forexample, the crank E.

, The picture books F are mounted on the links of the chain G, whichpasses over the drum B. The chain is held taut by passing under the drumB rotatably mounted on the frame H, the latter slidably mounted onthe'standard, and held downwardly, to make the chain taut, by thesprings I I.

At the top of the standard A is the detent I so located as to bend thecards backward to exhibit the pictures thereon one by one as the bookspass thereunder in succession.

This method of mounting and exhibiting these motion picture bookspresents a number of advantages not the least of which is theopportunity thus afforded of arranging the books'in pictorial sequenceon the chain in such manner that each book represents some particularscene, a sustained picture story, for example.

What I do claim as my invention, and Wish to protect by Letters Patentof the United States, is

1. In motion picture apparatus. the combination of a series ofarticirlatedly connected motion picture books, and means for exhibitingthe pictures of said books, the point of articulation of the connectingmeans lying, outside the plane of the books.

5.. In motion picture apparatus, the combination of a series of flexiblyconnected motion picture books, a drum of such external conformation asto detachably hold and give motion to said books daring the exhibitionof the pictures thereon, and means for supporting and rotating saiddrum. I

3. In motion picture apparatus, the combination of a series of flexiblyconnected [notion picture books, a drum having longitudinal groovestherein to receive, detachably hold and impart motion to said booksduring the exhibition thereof, and means for supporting and rotatingsaid drum.

in testimony whereof I have aifixcd my signature in presence of twowitnesses.
